Balrownie

[1] DERIVATION:

Old Red Sandstone rocks, principally sandstone with some erratics of Dalradian schist

TYPES OF PARENT MATERIALS MAPPED:

Glacial till, generally water-modified
Glacial drift, generally water-modified or onto rock
Shattered rock in situ
Deeply weathered rock

COLOUR:

Distinctive reddish brown colour within subsoil

TEXTURE:

Sandy loam water-modified material within the upper 60cms overlying sandy silt loam or clay loam at greater depth. Slightly to moderate stony.

DOMINANT LAND USE:

Arable, some forestry and limited recreation.

LANDFORMS

Undulating lowland and foothills with gentle or moderate slopes, all landforms generally free from rock outcrop.

SOIL CHEMISTRY:

Moderately acidic with low or medium percentage base saturation in subsoil but high in fine-textured parent material. Low total phosphorus in subsoil.

SOIL PHYSICAL PROPERTIES:

35-60cm depending on thickness of water-modified material or presence of rock.
Till compact at depth and lacks structure.
